Hydrazinium hydroxide solution Usage And Synthesis

Chemical Properties

clear colorless solution

Uses

Hydrazine hydrate may be used to prepare:

• 3-(2-Benzyloxy-6-hydroxyphenyl)-5-styrylpyrazoles by reacting with 5-benzyloxy-2-styrylchromones.
• 3,5-Diphenyl-2-pyrazoline derivatives by reacting with 1,3-diphenyl-2-propen-1-one.
• 3′-Aryl-1,2,3,4,4′,5′-hexahydrospiro[quinoxalin-2,5′-pyrazol]-3-ones by reacting with 3-arylacylidene-3,4-dihydroquinoxalin-2(1H)-ones.
• It may also be used in the catalytic reduction of nitroarenes to aromatic amines.

Uses

Hydrazine hydrate solution has been used as a reducing agent for tellurium oxide during the preparation of tellurium nanowires.

Definition

ChEBI: Hydrazine hydrate is a hydrate. It contains a hydrazine.

General Description

The addition of hydrazine hydrate to reduced graphene oxide (RGO) counter electrode improves its performance in dye-sensitized solar cells (DSSC).

Purification Methods

Hydrated hydrazine can be obtained as above and diluted as required. Solutions containing various amounts of H2O are available commercially.
